Geochemical Niches of Iron-Oxidizing Acidophiles in Acidic ,
A legacy of coal mining in the Appalachians has provided a unique opportunity to study the ecological niches of iron-oxidizing microorganisms Mine-impacted, anoxic groundwater with high dissolved-metal concentrations emerges at springs and seeps associated with iron oxide mounds and deposits These deposits are colonized by iron-oxidizing microorganisms that in some cases efficiently remove ....
